1. What is the main purpose of a load chart on a crane?
A. To determine wire rope wear
B. To identify the crane’s lifting capacity at various configurations
C. To track operating hours
D. To document operator performance
Load charts provide crucial information about the crane's rated
lifting capacity based on boom length, angle, radius, and
configuration.
2. What should a crane operator do before lifting a load for the first time
on a job site?
A. Immediately begin the lift
B. Perform a trial lift to test the load and crane response
C. Call a signal person
D. Notify OSHA
A trial lift confirms the load is within capacity and the crane functions
safely before performing the actual lift.
,3. What does "D/d ratio" refer to in rigging?
A. Drum diameter to rope length
B. Diameter of the object to the diameter of the rope
C. Distance to destination
D. Downward deviation
The D/d ratio is the ratio of the diameter of the load to the diameter
of the rope and affects rope performance and safety.
4. According to OSHA, what is the minimum distance a crane must
maintain from a 50 kV power line?
A. 5 feet
B. 10 feet
C. 15 feet
D. 20 feet
OSHA requires a 10-foot minimum distance for up to 50kV, but for
voltages over 50kV, it increases (e.g., 15 feet for 50–200kV).
5. Who is responsible for determining the weight of the load to be lifted?
A. Signal person
B. Supervisor
C. Crane operator
D. Engineer
The crane operator must verify the load weight before lifting to
ensure it is within capacity and safe to handle.
6. What is the function of outriggers on a mobile crane?
A. Add weight
B. Stabilize the crane during lifting operations
C. Increase boom height
D. Assist with steering
Outriggers extend from the chassis to provide additional stability and
prevent tipping during lifts.
, 7. What type of inspection is required after a crane has been modified or
repaired?
A. Monthly inspection
B. Annual inspection
C. Shift inspection
D. Post-repair inspection
OSHA requires a post-repair inspection to ensure the crane is safe
after any structural or functional modification.
8. What must a crane operator do if wind speeds exceed the
manufacturer’s safe operating limit?
A. Operate slowly
B. Continue as normal
C. Cease crane operations immediately
D. Reduce the load by 50%
High wind conditions pose a hazard; operations must stop if limits
are exceeded according to manufacturer specifications.
9. What hand signal indicates “emergency stop”?
A. Thumb down
B. Arm extended, palm down, moving hand rapidly left to right
C. Closed fist
D. Index finger circling
The “emergency stop” is a universal hand signal used to immediately
halt crane operations for safety.
10. Which of the following requires a certified signal person on site?
A. Always
B. Only during night operations
C. When the operator’s view is obstructed
D. When using a mobile crane
